Common question: “My Valve makes a noise randomly.”
The valves carry out a weekly motor test, however some reports suggest that it may be done at the wrong time – such as in the middle of the night.
To counter this, Removing and refitting the batteries will reset the valve and reset the timer of the test.
The vale does the exercise routine at 11:00am on a Thursday. When the batteries are removed and refitted in the valve the day and time is set to 00:00 and day 0 (this is Midnight between Saturday/Sunday). So, assuming that the ‘valve learning’ is going to be 4 days and 11 hours after the valve is restarted then we would suggest removing and re-inserting the batteries (remembering to press the left or right button when the batteries are not in the valve so the valve knows the batteries have been removed) any time between 22:00 and 10:00. I.e. if you reset the valve during the night then the valve exercise routine will happen during the day time.
